abstract = {Background: Pulmonary pleomorphic carcinoma has made an unfavorable prognosis because of its properties of resisting radiation and chemotherapy, and its aggressive growth. The correlation between clinicopathological factors and prognosis about pulmonary pleomorphic carcinoma patients who received its surgical resection has not been clearly identified.
Methods: We retrospectively investigated the clinical records of 24 pulmonary pleomorphic carcinoma patients who had a surgical resection from January 2004 to December 2013 at our institute. We examined the correlation between their clinicopathological factors and therapeutic effects including their prognosis.
Results: The median follow up time was 2.3 years. The 5-year survival was 54.7% and the 5-year progression free survival was 52.4%. In comparison with other tissue types of lung cancer, the prognosis was not so poor even taking into consideration the survival curve including several progression stages. We analyzed the 21 clinicopathological factors in order to clarify the factors connected with the prognosis and disease progression. As a result, we found that both vascular invasion evaluated by immunohistochemistry and lymph node metastasis were connected closely with the overall survival. We found another strong link between the tissue type of epithelial components, vascular invasion evaluated by immunohistochemistry and lymph nodal metastasis with the progression free survival.
Conclusions: Pulmonary pleomorphic carcinoma patients with lymph node metastasis and vascular invasion had worse prognosis after their surgical resections. We have to find an effective chemotherapeutic drug or molecular targeted drug.},
